ARU Acid Gad Pre-heater Technical Details
1. Shell Material: Killed Carbon Steel
2. Tube Bundle Material: Alloy Steel
Impact Testing: Conducted in accordance with Russian standards to ensure the material's toughness at low temperatures, especially for applications in harsh operating environments.
Hardness Testing: The maximum allowable hardness for the material is 225HB, ensuring durability and resistance to wear while maintaining ductility.
3. U-Bent Tubes: Stress Relief After Bending The heat exchanger tubes are precision U-bent to meet the design requirements. After bending, the tubes undergo stress relief treatment in accordance with ASME UCS-56.
4. Post-Weld Heat Treatment (PWHT) All welded components of the heat exchanger are subjected to Post-Weld Heat Treatment (PWHT) as per ASME standards.

This acid gas pre-heater bundle is engineered for sulfur recovery unit service, where process gas temperatures and corrosive species place real demands on materials and joint integrity. The U-tube configuration handles differential thermal expansion between the bundle and shell, while 304 stainless steel construction resists the corrosive attack typical of acid gas service. Fabricated under ASME U Stamp with CE certification, the bundle is built to match your existing shell envelope and tubesheet pattern for a direct replacement. Complete documentation, including material certificates and test reports, is supplied with installation support from our engineering team.
